A wide-angle electron grating bi-prism beam splitter

We demonstrate a wide-angle electron beam splitter capable of producing 1 cm beam separation at the detection plane. The beam splitter utilizes a nanofabricated periodic grating in combination with a bi-prism element. In contrast to devices utilizing only bi-prism elements, the use of the periodic grating causes amplitude, and not wavefront, splitting. Even at maximum separation, beam profiles ...

Prism grating using polymer stabilized nematic liquid crystal

A prism grating using polymer stabilized liquid crystal was fabricated and its diffraction characteristics evaluated. Such a prism grating exhibits not only a periodic grating structure but also a prism-like gradient refractive index within each grating period. As a result, the diffraction behavior is asymmetric. The first order exhibits high diffraction efficiency while the zeroth order has a ...

EMISSION-LINE OBJECTS FROM A PRELIMINARY UKST OBJECTIVE PRISM SURVEY

A visual search has been made of four fields using United Kingdom 1.2m Schmidt Objective Prism plates with a reciprocal dispersion of 1 180 A/mm at HP. Such plate material is ideally suited to searches for emission-line galaxies. We present a catalogue of 53 emission-line objects, which comprises 45 galaxies, where individual HI1 regions are resolved in 16 bright galaxies; 8 are emission li...

Hamlet and Hamletism through the prism of the creativity of M. Lermontov and A. Blok

The author of the article aims to explain world literature through such concepts as the concept of Hamletism and the character of Hamlet in relation to selected works of Russian Romanticism, in particular, the beginning of realism and symbolism as an outstanding current of the Silver Age. Subject of a careful comparative analysis is the works of Mikhail Lermontov ("Demon" and "Ma...
